The moving means for moving within the screen, the specifying means for specifying another symbol image at the destination of the moved symbol image, and the group information to which the slave unit corresponding to the moved symbol image belongs is specified. Was Change means for changing to group information to which the handset corresponding to the symbol image belongs to, the display control means displays the moved symbol image so as to return to the display position before the movement, and The display means is controlled to display the changed group information.

  According to the present invention, the display includes a screen in which a predetermined symbol image representing each of a plurality of performance learning slave units connected to the connection means is arranged in accordance with a predetermined actual positional relationship of the slave units. Display on means. An arbitrary symbol image is designated from among a plurality of symbol images displayed on the display means, and the designated symbol image is moved within the screen, so that the moved symbol image is moved to the destination. A certain other symbol image is specified, and group information to which a child device corresponding to the moved symbol image belongs is changed to group information to which a child device corresponding to the specified other symbol image belongs. Therefore, the user can easily and efficiently set the grouping of students. Further, the moved symbol image is displayed so as to return to the display position before the movement, and the screens displayed before and after the movement are arranged in accordance with a predetermined actual arrangement positional relationship of the slave unit. Because the screen is the same in that it is the same screen, the user always has each student (child machine) that is actually located in the classroom regardless of the grouping status using the screen. The correspondence with the group to which each student belongs can be grasped at a glance.

  The present invention can be constructed and implemented not only as a device invention but also as a method invention. Further, the present invention can be implemented in the form of a program of a processor such as a computer or a DSP, or can be implemented in the form of a storage medium storing such a program.

Use an electronic musical instrument placed in a classroom simply by specifying a desired image on the screen and moving the specified image so that it overlaps another image. Since the students to be grouped are grouped into the same group, the user can easily and efficiently set the grouping of the students.

  Embodiments of the present invention will be described below in detail with reference to the accompanying drawings.

  FIG. 1 is a hardware configuration block diagram showing an embodiment of the overall configuration of an electronic musical instrument to which the performance learning setting device according to the present invention is applied. The electronic musical instrument DM shown in this embodiment is controlled by a microcomputer including a microprocessor unit (CPU) 1, a read only memory (ROM) 2, and a random access memory (RAM) 3. The CPU 1 controls the operation of the entire electronic musical instrument. For this CPU 1, ROM 2, RAM 3, communication interface (I / F) 4, input operation unit 5, display unit 6, external storage device 7, and sound source 8 are respectively connected via a communication bus 1D (for example, data and address bus). It is connected. The ROM 2 stores various control programs executed by or referred to by the CPU 1, various data, and the like. The RAM 3 is a working memory that temporarily stores various data generated when the CPU 1 executes a predetermined control program, or a memory that temporarily stores a control program currently being executed and related data. used. A predetermined address area of the RAM 3 is assigned to each function and used as a register, flag, table, memory, or the like.

  The communication interface 4 is connected to, for example, a wired or wireless communication network such as a LAN, the Internet, a telephone line, and the like, and an electronic musical instrument DM for a leader operated by the leader via the communication network (according to the present invention). An electronic musical instrument to which a performance learning setting device is applied, which is called a parent machine) and one or more electronic musical instruments M (called a child machine) for one or more students who perform performance operations can be communicated with each other. And various information such as setting information generated based on the setting operation of each device and musical tone information generated based on the performance operation between the parent device DM and the child device M via the communication network. So that they can send and receive each other. Such a communication interface 4 may be both wired and wireless, and both.

  The input operation unit 5 is a performance operator such as a keyboard having a plurality of keys for selecting the pitch of a musical tone, a selection switch for selecting a musical piece or part to be learned, or a master unit DM. It is an operator such as a grouping switch for executing processing for dividing the connected slave unit M into a group desired by the user. The performance operators such as the keyboard can be used not only for musical performance, but also as input means for selecting a song or part to be displayed. Of course, in addition to these, the input operation unit 5 is a numeric keypad for inputting numeric data, a keyboard for inputting character data, or various devices such as a pointing device (for example, a mouse) used for operating a predetermined pointer displayed on the display 6A. An operator may be included. The display unit 6 corresponds to a large number of students (children's handsets) who simultaneously perform a performance lesson on a display 6A composed of, for example, a liquid crystal display panel (LCD), a CRT, etc., according to simple icon operations on the screen by the instructor. ) Can be divided into groups, as well as displaying a “classroom screen” (see FIG. 2 to be described later), a list of songs that can be targeted for performance training, parts assigned to slave units, and performance training targets This is for displaying various information such as the musical score of the tune or part, the device setting state for each parent device and / or child device, or the control state of the CPU 1. The instructor can appropriately display these information on the display 6A as necessary. While referring to these displays, the instructor can select groups of slave units, select music and parts for performance training, electronic Device settings such as settings related to musical instrument performance functions can be made. These settings made in the parent device DM can be reflected in one or more child devices M connected via the communication network X. In other words, the base unit DM can not only set itself, but can also set the base unit DM from the base unit DM.

  The external storage device 7 stores various control programs executed by the CPU 1 and various data (for example, “grouping process” described later (see FIG. 3) or performance data related to music for performance learning). If no control program is stored in the ROM 2, the control program is stored in the external storage device 7 (for example, a hard disk) and read into the RAM 3 to store the control program in the ROM 2. An operation similar to the case can be executed by the CPU 1. In this way, control programs can be easily added and upgraded. The external storage device 7 is not limited to a hard disk (HD), but can be attached in various forms such as a flexible disk (FD), a compact disk (CD), a magneto-optical disk (MO), or a DVD (Digital Versatile Disk). A storage device using an external recording medium may be used. Alternatively, a semiconductor memory or the like may be used.

  The tone generator 8 can simultaneously generate musical sound signals on a plurality of channels, and inputs performance data provided via the communication bus 1D or performance information generated in response to a user operation of the performance operator. A musical tone signal is generated based on the performance information. A musical sound signal generated from the sound source 8 is generated from a sound system 8A including an amplifier and a speaker. A predetermined effect may be applied to the musical sound signal generated from the sound source 8 using an effect circuit or the like (not shown). The performance data format may be digitally encoded such as MIDI format, or may be a waveform sample data system such as PCM, DPCM, ADPCM. Any conventional configuration may be used for the configuration of the sound source 8 and the sound system 8A. For example, the sound source 8 may employ any of various tone synthesis methods such as FM, PCM, physical model, formant synthesis, etc., or may be constituted by dedicated hardware, or by software processing by the CPU 1. Also good.

  In the above-described electronic musical instruments (master machine DM and slave machine M), the performance operator is not limited to a keyboard instrument, but may be any type of instrument such as a stringed instrument, a wind instrument, or a percussion instrument. In addition, the electronic musical instruments (master device DM and slave device M) are not limited to those in which the input operation unit 5, the display 6A, the sound source 8 and the like are built in one electronic musical instrument body, but each is configured separately, and has a MIDI interface and various types. Needless to say, each apparatus may be configured to be connected using a communication interface such as a network. Furthermore, the device to which the performance learning setting device according to the present invention is applied is not limited to the form of an electronic musical instrument, and a child operated by a student, such as a personal computer, a portable communication terminal such as a mobile phone, a karaoke device, or a game device. As long as it can be communicably connected to the apparatus, the present invention may be applied to any form of apparatus or device.

  Here, in a “classroom screen” (see FIG. 4) described later, which is stored in the external storage device 7 or the like, a predetermined electronic musical instrument image (preliminarily prepared) symbolizing a child device actually arranged in the classroom. "Slave unit information" referred to for displaying predetermined information associated with each slave unit as character information and the like together with symbol images such as icons and thumbnails). FIG. 2 is a conceptual diagram showing an embodiment of the data structure of handset information.

  The child device information only corresponds to the electronic musical instrument image on the “classroom screen” displayed on the display 6A (that is, only corresponds to the existing electronic musical instrument for the student who is actually arranged in the classroom). Record information about the handset. As shown in FIG. 2, the information about the child device includes a child device number, a student name, group information, attendance information, and other information. The handset number is a unique number that is arbitrarily assigned in advance to each electronic musical instrument (slave handset M) for students actually placed in the classroom. Here, an example is shown in which 16 child devices M are actually arranged in the classroom, and each child device M is assigned a child device number from “1” to “16”. The student name is the name of the individual student who receives the performance lesson using the handset M actually arranged in the classroom. About this student name (in the example shown, Mr. A to Mr. P), each instructor uses a predetermined “setting screen” (not shown) before the instructor starts the first performance lesson. It is possible to input for each child device M assigned to, or to enable the student himself / herself to input from the child device M assigned to be used before the performance lesson is started. There may be.

  The group information is information for dividing a large number of students who perform performance learning at the same time into a plurality of groups such as by level and by part. In accordance with this group information, a large number of students (but only attendees) receiving performance lessons can be divided into multiple groups, and the instructor performs the same performance for the students belonging to each group. This makes it easy to learn at the same time or for each individual. In the embodiment shown here, an example is shown in which only attendees among 16 students are divided into three groups G1 to G3. The first group (G1) includes 4 students “A, C, D, E”, and the second group (G2) includes 4 students “F, H, I, L”. The number of students included in the third group (G3) is “M, P”. Absents are not grouped. A predetermined color is combined with the group number of the group information, and the color designated for each group number is a slave unit when an electronic musical instrument image (slave unit icon HC) is displayed on the “classroom screen”. Used when the icon HC is colored and displayed. The color assigned to each group number may be assigned a predetermined color, or the user may arbitrarily designate the assigned color. In addition, for the absentees who are not grouped (see attendance information described later), the “gray” color is uniformly assigned here.

  Attendance information is information indicating the attendance status of each student at the time of one performance lesson, and here, attendees are represented as “out” and absentees as “absent”. This attendance information is automatically registered as “Attendees” when the electronic musical instrument (slave device M) for students assigned in advance for use by each student is turned on. When the (slave device M) is turned off, it is automatically registered as “absent”. That is, even if the student actually attends the lesson, it is treated as “absent” unless the power of the handset M to be used is turned on. Of course, the present invention is not limited to this, and the instructor can input the attendance status of each student for each slave device M by using the master device DM after visually confirming the attendance status of each trainee visually. May be. Alternatively, when the child device M is powered on, when any operation is performed for the first time using the child device M, or when attendance is input by the student himself / herself, those child devices M Students who use may be registered as “Attendees”. Other information is information other than those described above, for example, information on the subject song / part that is being learned, setting information (for example, timbre / effect) regarding the musical tone of each electronic musical instrument, and classroom number (teaching system ID) Such information may be used.

  Next, after displaying a “classroom screen” (see FIG. 4), which will be described later, on the display 6A, a “grouping process” for grouping students according to user operations on the displayed “classroom screen”. Will be described with reference to FIG. FIG. 3 is a flowchart showing an example of the “grouping process”. This process is a process that is executed on the electronic musical instrument DM (master device) side for the instructor and is started in response to the operation of the grouping switch by the instructor.

  Step S1 executes a process for displaying the “classroom screen” on the display 6A. As will be described in detail later, the “classroom screen” displayed on the display 6A is in the classroom of the electronic musical instrument DM (master device) for instructors and the electronic musical instrument M (slave device) for students that actually exist in the classroom. A predetermined electronic musical instrument image (a symbol image that symbolizes an electronic musical instrument such as the parent device icon HO and the child device icon HC) is displayed so as to have the same arrangement positional relationship in the screen in accordance with the arrangement positional relationship in FIG. In addition, a GUI (Graphical User Interface) screen displaying a predetermined operation button image is displayed below (see FIG. 4 described later). Such a “classroom screen” is displayed according to symbol images (such as a parent device icon HO and a child device icon HC) created by the user in advance and display layout information, and the display method of such a screen is conventionally known. Therefore, the description here is omitted. In step S2, the attendance status is confirmed for each student who uses the electronic musical instrument M (slave device) for the student who actually exists in the classroom. For example, the attendance check of the student automatically detects that the main body power switch of the slave unit M assigned in advance to be used by each student is turned on / off by the student. Accordingly, when it is detected that the child device M is in the power-on state, the student assigned to use the child device M is treated as “attendance”, while the child device M is in the power-off state. If this is detected, the student assigned to use the child device M is treated as “absent”. Then, the “Attendance information” (see FIG. 2) of the above-mentioned child device information is updated, and the display color of the electronic musical instrument image (child device icon HC) of the absent person in the “classroom screen” is preliminarily combined based on this. Change to the color that is displayed (here “gray”).

  In step S3, it is determined whether or not a selection operation of the “setting” button B2 (see FIG. 4) of the “classroom screen” has been detected. For example, the user (instructor) selects the “setting” button B2 by, for example, clicking the pointer P on the “setting” button B2 on the “classroom screen” by using the mouse or the keyboard. There are modes of operation. When the selection operation of the “setting” button B2 is detected (YES in step S3), a “setting screen” (not shown) is displayed separately as being superimposed on the “classroom screen” being displayed as a pop-up screen, for example. Using the “setting screen” by the user (instructor), input of subject music / parts to be performance-trained, input of setting information (for example, timbre / effect) related to musical sounds of electronic musical instruments, etc. In response to this, the “other information” (see FIG. 2) of the slave unit information is updated (step S4). At that time, the user can immediately return the display on the display 6A to the “classroom screen” by performing an operation of closing the “setting screen” being displayed.

  In step S5, it is determined whether or not a selection operation (for example, a click operation) of the “end” button B3 (see FIG. 4) of the “classroom screen” has been detected. When the selection operation of the “end” button B3 is detected (YES in step S5), the process ends. In step S6, it is determined whether or not a selection operation (for example, a click operation) of the “automatic grouping” button B1 (see FIG. 4) on the “classroom screen” has been detected. When the selection operation of the “automatic grouping” button B1 is detected (YES in step S6), the screen is displayed on the display 6A of the parent device DM so that the instructor selects the grouping rule (step S7). ). A “selection screen” (not shown) for selecting a grouping rule may be displayed separately, for example, so as to overlap the “classroom screen” being displayed as a pop-up screen or the like. Then, grouping is automatically executed according to the grouping rule selected on the “selection screen”, and “group information” (see FIG. 2) of the slave unit information is determined according to the result of this automatic grouping. At the same time, the display of each child device icon HC on the “classroom screen” is updated (step S8). The display of each child device icon HC in the “classroom screen” is updated by the display color of the electronic musical instrument image (child device icon HC) in the “classroom screen” corresponding to the group of students grouped based on automatic grouping. Is changed to the same color for each group, and the child device number (child device 1, child device 2,... Shown in FIG. 4 described later) and the name of the student (described later) are displayed as character information. In addition to Mr. A, Mr. B, etc. shown in FIG. 4, the name of the group to which each student belongs (G1, G2,... Or, it is displayed near each handset icon HC.

  Here, the grouping rule is a rule for determining, for example, how many students form one group (for example, which number of people, such as 2/4/8 people, etc.). By selecting the rule, the instructor selects a large number of attendees for each performance lesson in a predetermined unit such as “2/4/8”. Can be grouped automatically. Specifically, when a rule for grouping so that one group is formed in units of “4 students” is selected, the slave unit used by attendees treated according to the slave unit information shown in FIG. Are grouped according to an automatic grouping rule (four people each here) in the order of unique numbers (by skipping the processing of slaves used by absentee students). However, at the time when processing of the slave unit used by attendees who are attended at the end of grouping is completed, the group to which the slave unit (student) grouped last belongs belongs to four students. If not, the less than four students are grouped into one group, and the automatic grouping process ends.

  In step S9, it is determined whether or not a selection operation of the child device icon HC (see FIG. 4) on the “classroom screen” has been detected. Here, as an operation of selecting the child device icon HC on the “classroom screen”, for example, the user uses the mouse or keyboard to position the pointer P on the arbitrary child device icon HC in the screen and click the mouse. There is an operation mode (so-called click operation). The selection operation of the child device icon HC is not limited to selecting one child device icon HC, and a plurality of child device icons HC may be selected at once. When the selection operation of the child device icon HC is detected (YES in step S9), the display position (movement source position or position) of the selected child device icon HC in the “classroom screen” when the child device icon HC is selected. The click position is temporarily stored (step S10). In step S11, it is determined whether the selected state of the same child device icon HC is maintained. When the selection state of the same child device icon HC is maintained, for example, while the state in which the mouse is clicked by the operation by the user is maintained (when step S11 is YES), the processing is temporarily stopped. Wait. When the selected state of the same child device icon HC is not maintained, for example, when the user clicks the mouse and then the clicked state is released, and the clicked state of the mouse is not maintained ( In step S11, it is determined that the child device icon HC has been dropped, and the child device icon HC at the time when the selected state of the same child device icon HC is released (that is, at the time of drop operation). The display position (movement destination position or drop position) in the “classroom screen” is detected (step S12).

  In step S13, it is determined whether or not the movement destination position of the detected child device icon HC is outside the “classroom screen” frame (specifically, outside the grouping setting region KG shown in FIG. 4 described later). When it is determined that the destination position of the child device icon HC is outside the “classroom screen” frame (YES in step S13), the students who use the child device corresponding to the child device icon HC are put into a new group. Grouping is performed (step S14). That is, each student is removed from each group after moving the handset icon HC from the group to which each student belonged before the handset icon HC was moved, and only one new group is left with the left students. The child device information is updated so that When a group that has not yet been assigned is newly assigned, a group to which a student (student) is not assigned is searched by referring to the slave unit information (see FIG. 2), and the found group is assigned. Here, as an example of a method for finding a group to which a student (student) is not assigned, for example, the group information of the slave unit information shown in FIG. 2 is searched, and a group number not registered in the slave unit information is newly found. Allocate as a group. After the process of step S14 is completed, the process jumps to the process of step S17.

  On the other hand, if it is determined that the movement destination position of the child device icon HC is not outside the frame of the “classroom screen” (NO in step S13), the movement destination position of the child device icon HC is within the frame of the “classroom screen” (specifically In step S15, it is determined whether it is over another child device icon HC (within a grouping setting area KG shown in FIG. 4). That is, it is determined whether or not the child device icon HC that has been clicked has been dropped in a state where at least a part thereof is superimposed on another child device icon HC. If it is determined that the destination position of the slave unit icon HC is above another slave unit icon HC (YES in step S15), the group information of the slave unit information is referred to, and the other destination location The group information of the slave unit corresponding to the slave unit icon HC is acquired, and the same group as the acquired group information is assigned to the slave unit corresponding to the dragged slave unit icon HC, and the slave unit information is updated. (Step S16).

  In step S17, referring to the updated latest slave unit information, the dragged and dropped slave unit icon HC is selected from the destination position when the slave unit icon HC stored temporarily is selected. The display is returned to the display position (movement source position) in the “classroom screen” (step S17). That is, the display position of each child device icon HC on the “classroom screen” is not changed before and after the drag-and-drop operation of the child device icon HC desired by the user. However, the group is changed and displayed. In step S18, it is determined whether or not another learning operation using the “classroom screen” (see FIG. 4) has been detected. As other learning operations, there are performance techniques such as fingering and playing strength and lesson instructions such as musical guidance (advice), etc., for the slave unit M corresponding to the slave unit icon HC designated on the screen. When other learning operation is detected (YES in step S18), processing corresponding to the detected operation is executed (step S19). After the process of step S19, the process returns to the process of step S3 and the above-described processes from step S3 to step S19 are repeatedly executed.

  Next, FIG. 4 shows a “classroom screen” used for appropriately classifying a large number of students who perform performance learning at the same time, depending on the level of the students and parts of the music to be performed. It explains using. FIG. 4 is a conceptual diagram showing an example of a “classroom screen”.

  The “classroom screen” shown in FIG. 4 is a GUI (Graphical User Interface) screen that is displayed in accordance with the size of the display 6A, more specifically, the size of the display window. Here, it is a user interface screen that is used frequently and can perform most operations related to grouping of students by operating a pointing device such as a mouse. The “classroom screen” shown in this embodiment is roughly divided into a grouping setting area KG for grouping based on user operations and a button setting area BG for displaying operation buttons. The grouping setting area KG includes a parent device icon HO corresponding to an electronic musical instrument DM (parent device) for instructors and a child device icon HC corresponding to an electronic musical instrument M (child device) for students. Is displayed at a display position on the screen in accordance with the positional relationship of the actual electronic musical instruments that are actually arranged. Here, a screen display example in the case of a classroom where the child devices are actually arranged in 4 × 4 rows as viewed from the parent device is shown. In the child icon HC or in the vicinity thereof, a unique child device number (child device 1, child device 2,...) Assigned to each electronic musical instrument in advance and each child device are used in accordance with the child device information. In addition to the assigned student names (Mr. A, Mr. B,...), The group names (G1, G2,...) To which each student belongs can be displayed. Yes. Of course, before the grouping operation of the students, the group number does not have to be displayed as all the students do not belong to any group, and all the students belong to the same group. The same group number may be displayed as being present. The button setting area BG displays operation button images such as an “automatic grouping” button B1, a “setting” button B2, and an “end” button B3.

  As the power of each slave unit is turned on by the student before the performance lesson starts, the display color of the slave unit icon HC on the screen corresponding to the power-on at any time is “gray” indicating that the person is absent The color is changed to a predetermined color assigned to each group indicating attendance (attendance confirmation). In other words, the handset icon HC corresponding to the handset that is not attended by the student and remains in the power-off state remains in “gray” color display (the handset 2 and handset 7 shown in the figure). (Refer to handset 10, handset 11, handset 14, handset 15). In such a state, for example, when a grouping rule that constitutes one group with “4 people” is selected and the “automatic grouping” button B1 is operated, four people from attending student A in order In other words, 4 people of “A, C, D, E” are less than 4 people in the first group (G1) and 4 people of “F, H, I, L” are in the second group (G2). Are grouped into a third group (G3). Then, according to this automatic grouping, the display color of each child device icon HC is changed to a color already assigned to each group.

  As a result of the above automatic grouping, only Mr. M (child machine 13) and Mr. P (child machine 16) have become a group of only two people. For example, M is the first group and M is the second. If the student wants to divide the students into two groups, the instructor sets the child device icon of the child device 13 on the child device icon of the child device 5 and the child device icon of the child device 16 on the child device 12. Drag and drop each on the handset icon. Specifically, the slave unit icon of the slave unit 13 (or the slave unit 16) is designated according to the click operation, and the slave unit icon of the clicked slave unit 13 (or the slave unit 16) is designated as the slave unit 5 (or the slave unit). The slave unit icon of the slave unit 13 (or the slave unit 16) is overlapped with the slave unit icon of the slave unit 5 (or the slave unit 12). In this state, by dropping the child device icon of the child device 13 (or the child device 16), the child devices using the child device corresponding to the dragged and dropped child device icon are overlapped. Transfer to the group to which the students who use the handset corresponding to the icon belong. In the above case, Mr. M of the slave unit 13 is incorporated into the first group to which Mr. E of the slave unit 5 belongs, so that the group display indicating that the slave unit icon of the slave unit 13 belongs to the third group (G3 ) To a group display (G1) indicating that it belongs to the first group. On the other hand, since Mr. P of the handset 16 is incorporated into the second group to which Mr. L of the handset 12 belongs, the icon of the handset 16 belongs to the second group from the group display (G3) indicating that it belongs to the third group. The display changes to a group display (G2) indicating that it belongs. Note that the slave icon that has been dragged and dropped is displayed so as to automatically return from the dropped position (movement destination position) to the clicked position (movement source position). In other words, before and after the grouping is performed, the display position relationship of each child device icon HC on the “classroom screen” is not affected by the drag-and-drop operation of the child device icon HC. No changes are made.

As described above, by clicking and dragging and dropping the child device icon on the “classroom screen”, the student using the child device associated with the dragged child device icon and the dragged child Users who use the slave unit that is associated with the slave unit icon that is superimposed when the unit icon is dropped are grouped so that they belong to the same group. Therefore, it becomes possible to easily group a large number of students.
In addition, even if grouping is performed according to the drag and drop operation of the child device icon as described above, the display positional relationship in the “classroom screen” of the child device icon that has been dragged and dropped is not changed. Therefore, the user can visually grasp the correspondence between each student (child machine) that is actually located in the classroom and the group to which each student after grouping displayed on the screen belongs. Can be easily done.

In the above-described embodiment, grouping by drag & drop operation of the child device icon HC on the “classroom screen” is executed according to the operation of the mouse. Grouping may be performed in accordance with the movement of the pointer P using the body type display device. Alternatively, a tablet or a trackball may be used.
In addition, although the subunit | mobile_unit icon HC displayed on a "classroom screen" is made into the icon which displayed the group number and the student name, it may be a symbol icon, for example. In that case, you may make it display by changing a symbol for every group.

Note that the “classroom screen” shown in the above-described embodiment may be displayed over a plurality of pages. In that case, grouping of students may be possible only within one displayed page, or may be possible across different pages. To enable grouping across different pages, for example, a page switching button is placed in the “classroom screen”, and the page is switched by dragging and dropping the slave unit icon HC on the button. It is preferable to display the child device icon HC selected on the previous page on the top so that the user can drag and drop it again.
Note that the color of the child device icon HC of the absent person may not be uniformly displayed in “gray” color, and may be displayed by changing the color for each group to which the absent person belongs. In addition, absentees may be treated as “no group”.
Note that the display color of the child device icon HC assigned to each group may be set freely by the user through a “setting screen” (not shown).
In the above-described embodiment, the drag and drop operation of the child device icon HC to the outside of the “classroom screen” frame is shown as an example of the group cancellation operation. However, the present invention is not limited to this. You may make it recognize the drag and drop to the location where the icon HC is not displayed as operation for group cancellation | release. In this case, not only a group that is not yet assigned to a child device after group cancellation is newly allocated, but all the child devices after group cancellation may be set to “group unassigned”.

In addition, although the example which performs automatic grouping according to the grouping rule which prescribed | regulated the number of people (2 persons / 4 persons / 8 persons etc.) which comprise 1 group was shown, it cannot be overemphasized that another method may be sufficient. . For example, this is a method of grouping according to the progress of the tasks given by the instructor to the students, the skills of each student, or the position of the electronic musical instrument in the classroom (vertical column or horizontal column). May be.
The attendance check for students using the handset is automatically detected by signals generated when the handset is turned on, but the instructor visually confirms the attendance status of the attendees for each handset. However, the setting operation may be performed manually on the base unit side.
Note that the drag-and-drop operation of the child device icon HC is not limited to the operation for each child device icon HC, but a plurality of child device icons HC are simultaneously selected by, for example, a range designation operation using a mouse, and the like. A plurality of students may be grouped or ungrouped by dragging and dropping the icon HC at the same time.
It should be noted that, when grouping, drag and drop is performed so as to be superimposed on the child device icon HC belonging to the target group. However, an allowable range of several dots is set around each child device icon HC. If it is within the range, it may be considered that it is superimposed on the child device icon HC and grouped. Further, when a plurality of adjacent child device icons HC belong to the same group, any area located between the child device icons HC is regarded as being superimposed on the child device icon HC and grouped. You may do it.
